CREEL OR, SPOOL STAND.

Application filed. January To all whom it may. concern Be it known thatI, RAYMOND 0. LONG- VALL, a citizen of the United States, residing atWorcester, in the county of lVorcester and Commonwealth ofMassachusetts, have invented a new and useful Improvement in a Creel orSpool Stand, of which the following, together with the accompanydrawings, is a specification. Y

My invention relates to creels or spool stands, such as are employed forrotatably supporting a plurality of spools or yarn packages so that theyarn or thread may be conveniently led therefrom for winding on a wrapbeam, or for any other purpose.

The object of my invention is to provide an improved creel, or spoolstand, in which a large number of spools or packages may be mounted soas to occupy a minimum amount of floor space, and in which the spools orpackages can be readily dofi'ed and replenished. My inventioncontemplates a creel comprising a number of similar sections in each ofwhich the thread guides and thread boards are so arranged that all ofthe threads from one or more given series of spindles may be lifted by asingle operation so as to enable the opera tor to doif the exhaustedpackages and re place them with fresh packages without disturbing theremainder of the threads handled by the creel. The above andotheradvantageous features of my invention will hereinafter more fullyappear, reference being had to the accompanying drawings in which Fig. 1is a plan view of a complete creel or spool stand embodyingmy'invention.

Fig. 2 is a view in end elevation showing one of the sections of thecreel of Fig. 1, on an enlarged scale.

Fig. 3 is a perspective view of a portion of the section shown inFig. 2and illustrating the position normally occupied by the thread guides andthread boards.

Fig. 4 is a perspective view illustrating the position occupied by thethread guides and the thread boards when doffing.

Fig. 5 is a diagrammatic view illustrating the passage of the threadsfrom a given row of supplies.

Like reference characters refer to like parts in the difierent figures.

Referring to Fig. 1, the improved creel.

5, 1925. Serial No. 637.

comprises a number of sections numbered 1, 2 and 3, arranged in tandem,it being obvious however, that any other desired number of creelsections may be employed. The creel sections 1, 2 and 3 aresubstantlally identical in construction, so that it will only benecessary to describe the first or yarn packages 6, from which thethreads 7 are led to my improved thread guiding and handling mechanismwhich will now be described. i

As best shown in Fig. 3, a number of bars 8 are supported betweenvertical standards 9, the number of bars 8 corresponding to the numberof horizontal rows of spindles 5 and each bar 8 being provided withthread eyes 10 corresponding in number and in spacing to the spindles 5in a given row. Each bar 8 is carried by armsll pivotally attached tothe standards 9, and during the normal operation of the creel the arms11 hang downwardly to bring'the thread eyes 10 of each arm insubstantial alinement with the spaced spindles 5 of the correspondingrow. With this arrangement each thread 7 is taken off its package 6symmetrically with respect to the axis of the corresponding spindle 5,and

all of the threads 7 from a given row of spindles 5 are thus disposed insubstantially the same horizontal plane as they-are drawn through thethread eyes 10.

A thread board 12 is suitably secured to eachbar 8 and one of itssupporting arms 11, with the plane of the board 12 substantially atright angles tothat portion of the bar 8 in which the thread eyes 10 arecarried. The thread, board 12 is provided with a number of verticallyspaced rows of thread eyes 13, 14 and 15, the eyes 13 in the upper rowlying in substantially the same plane as the eyes 10 of the correspond.-ing bar 8. The several threads 7 passing throughth'e eyes '10 of a givenbar'8 are thus adapted to pass through the upper row of eyes 13 of thecorresponding thread board 12 inumoreior' less sheet form and withoutinterferingwwith each other, suitable tensioning devices 16 of a wellknown type being interposed between the eyes 10 and 13, if desired.

From a jointconsideration of Figs. 1-

and 3, it will be seen that the number of rows of eyes 13, l tand 15,carried by each thread 7board12 ocfthe forward section .1 corresponds tothe number of sections, it being obvious that the number of sections andspindles employed can be increased or decreased as desiredwithoutdeparting from myinventio-n. As previously stated, .the sections1,2 and 3 are substantiallyidentical in construction, corresponding.partsqbeing numbered the same and the only-difference being thatthethread boards 17 of the second section 2 are provided with one less rowof eyes '18 and '19 than the thread boards 12 oi the firstsection '1, asbest shown in Fig.3.

7 Similarly .thethreadboards of the last section 3 are provided with oneless-row of eyes 21 than the second SGCtiOIlJQ.

From the foregoingdescription itis apparent that thethreads 7 drawnfrom'any givenhorizontal row of spindles in all of the creel sectionswill pass through theleyes 13, 18 and21'ot the correspondingithreadboards 12, 17 .and20, respectively in substantially the same horizontalplane,.and without interference from eachother, .as indicateddiagramn'iatically in Fig. 5. In passing froma thread board 20 thethreads from the rearmostsection Sa-re deflected downward slightly top'ass'throu'gh first the eyes 19 of a thread .board 17, and. thenthrong-lithe eyes 15 of a thread board 12.

correspondingly, the threads passing from a thread board'l? of the nextpreceding'section 2 are deflected downward slightlyto p assthrough theeyes 14 eta threadboard 12,,so that all threads from a. given row ofspindles pass tromthe creel in three closely ,spacedplanes'and withoutinterference with each, other,

h'en it is desirediito dofi' packages on any given row of spindles .in asection,.the threadboard'of the corresponding row is lifted, asindicated in'Fig. 4, which shows,for

example, a portion of the first section.

"lVh'en the thread board 12 islitteld as shown, it .moves, about thepivotal. support :ot the arms '11 and carries with it the attachedbar '8and the eyes 10, thus moving all of the threads passing through thebar'8 above the planeof the corresponding set of "spindles 5. With thebar .8 in. itsraised position itis evident that the exhausted spindlesorpaek- V agesgca'n readily be defied and thespindles ,.replenis'hedwithout interfering with the threads passing through thelowerrows ofeyes1-i and 15 ofthexthread board 12," which are, ofcourse, lifted withthe threads passing through the upper row of eyes 13. In order tomaintain a thread board p12 and :its associated bar 8 in araisedposition, each thread board 12 is provided with a pivotallymounted prop 22 which normally hangs downwardly, as shown in Fig. 3, andis adapted to be turned to engage the stand ard 9 and thus hold thethread board in its elevated position, as shown in Fig. 1. When it isdesired to lower thethreadboard andbar after dotting itis' onlynecessary to turn the prop 22 downwardly, whereupon the threadboard 12will return to its normal horizontal position, as shownin-Fig; 3.

While it is evident} that any one of the thread boards 12, 17 and 20 maybe raised independently of allother threadbo'ardsin the creel, myinventon contemplates means whereby the raising of "a particular threadboard and bar will cause one or more of the thread boardsimmediatelyabove it to also be raised a limitedamount so as to preventany interference between the threads of the spindles'being dotted andthe threads oflthe' spindles immediately above. To this end each threadboard isprovided .with'laterally extending ears 23, which, as best shownin 1-, are adapted to engagethe' lower'edge of the threadboardimmediately above when the lower thread board has been raised athread board frornthe one being raised.

It is obvious that the vertical spacing between the rows of spindles in"any creelmay be suchas to resnlt inthe'raising of two ormorethreadboards in unison, or the vertical spacing may b'esuchlastopermit each thread board to be fully raised without. engaging the threadboardim-mediately above it. v

- It will be observed that in-any case, movement ot one or morethreadboa-rds or bars .I ll) in nowise slackens thetension on anythread,

nor allows any thread to hang down loosely, but. rather, as will beclearly seenjfrom "Fig. 4,

keeps each and every thre'adin a taut con creel, or spool stand, soarrangedthat one or more horizontallrows oflspindlesma-y be readilydoited and replenishedwithoutinter fering with the threads coming fromthe other spindles of the creel. Furthermore, a creel embodying myinvention lends itself to a very compact arrangement of spindles andpackages owing to the ease with which any number of spindles can bedoifed; consequently creels embodying my invention occupy a minimumamount of floor space.

I claim,
